What is a Contractor?

In the construction industry, a contractor is the party responsible for delivering a project or a portion of it, typically under a formal agreement with the project owner. Contractors oversee labor, materials, equipment, and scheduling to ensure work is completed according to the contract’s scope, quality standards, and timeline.

A general contractor (GC), sometimes called a prime contractor, manages the overall project and hires subcontractors to perform specialized work such as electrical, plumbing, or concrete. Whether a contractor is a GC or a subcontractor, they operate under legally binding terms that outline deliverables, payment schedules, and compliance requirements.

Being a contractor means navigating complex billing requirements—especially on the subcontractor side. Pay applications must match each client’s requirements, include precise documentation, and often wait on a chain of approvals before payment is released. Any hiccup (e.g., a missing lien waiver, the wrong form, an incorrect total) can push payment weeks or even months past due. In an industry where it already takes an average of 96 days to get paid, those delays can put serious strain on cash flow.

Siteline was built to help commercial subcontractors overcome these hurdles. Our software automates pay application creation, keeps lien waivers organized and compliant, and tracks payment status in real time. By streamlining the billing process, contractors using Siteline can avoid lengthy payment delays, strengthen relationships with GCs, and get paid faster.

Net D

What is Net D?

Net D, in the context of the construction industry, refers to the "net deliverable" square footage or area of a constructed property. It applies to the actual usable space that remains after the subtraction of communal areas such as shared hallways, staircases, and residential utilities from the gross square footage. In commercial real estate, it typically excludes areas reserved for mechanical systems, structural elements, elevator shafts, and similar components. This figure is critical as it impacts the leasing or selling value of a property and also informs space allocation, cost assessment, and planning considerations during a construction project. Therefore, understanding Net D is key to optimizing building layouts and the planning of space allocations within any construction project.

Cost Plus Billing

What is Cost Plus Billing?

Cost Plus Billing in the construction industry refers to a method where the customer agrees to cover the actual costs, expenses and other direct costs of the construction project plus an additional sum for contractor’s overhead and profit. These typically include costs of materials, labor, and subcontractor charges. The agreement clearly establishes and defines what is constituted as cost, the overhead percentage, and the profit percentage, reducing the risk of any surprise costs. Essentially, the 'Cost' represents the direct costs of the construction, while the 'Plus' is the contractor's fee and is usually agreed upon as a fixed percentage of the total costs or as a target price with a shared savings clause.

Actual Cost

What is Actual Cost?

Actual cost, in the construction industry, refers to the accurate amount reasonably spent on a project. This includes every expense incurred during the planning, development, and execution phases. The actual cost often encompasses material expenses, labor charges, equipment costs, and any additional overhead related to the project. For instance, the cost of bricks, cement, construction tools, and an hourly wage for workers constitutes the actual cost. It may differ from the estimated cost due to unforeseen circumstances or changes in the project scope. Monitoring the actual cost is vital for maintaining a project's budget and preventing financial oversights.
